To all whom it may concern Be it known that I, Gnonsn Pnoirorinw, a subject of the King of Great Britain, residing at Vulcan Works, Ravensworth Road,

Iensal Rise, in the county of London, England, engineer, have invented certain new and useful Improvements in or Connected with Automatic Machines for Packeting, lVeighing, and Delivering Given Quantities of Granular or Powdery Material, of which the following is a specification, reference being had to the drawings hereunto annexed and to the figures and letters marked thereon-that is to say:

The invention relates to improvements in or connected with automatic machines for packeting, weighing and delivering given quantities of granular or powdery material.

The primary object of the present invention is to obtain an automatic machine more especially intended for dealing with material in the form of powder and which will accurately weigh into packets or receptaoles given quantities thereof and deliver said filled packets ready for closing and that without any appreciable escape of dust from said material.

In the accompanying drawings Figure 1 is a front elevation of a machine constructed according to the present invention showing the parts in the position they assume at or approximately at the end of the weighing of afilled packet. Fig.2 is an end elevation thereof. Fig. 3 is a horizontal section taken on the line 11 of Fig. 1 but with some parts removed, and showing the pawl controlling the feed disk disengaged from the coacting ratchet wheel.

Figs. 9 to 12, 15 to 19, 25 to 80 and 32 to 36 are drawn to a further increased scale and Figs. 13, l t and 21 to 2% are drawn to a further increased scale with respect to the other figures of the draw ings.

(4 represents the frame of the machine which supports a table a to which are bolted two standards Z) and these standards have bolted to the upper part thereof cylindrical chambers 0* c in WlllCA are ar anged rotary cages or devices, hereinafter more fully referred to, for feeding and regulating the flow of the material and above one of these cylindrical chambers 0* c is a feed hopper 0 leading by a bifurcated channel 0 to the cylindrical chambers 0* 0 and which latter may be called the feed chambers. (See 1.)

Extending between the feed chambers 0* 0 and at its ends entering into each is shaft 0'' which is supported in bearin s c bolted to the exterior of the chambers 0* c and this shaft 0 for the sake of distinction will be ca led the feed shaft. (See Fig. 1.)

Upon the feed shaft 0" is fixed a chain wheel 0 which by means of a chain c is geared with a smaller chain wheel d loosely mounted upon a shaft (Z revolubly mounted in bearings carried by brackets (F from the taole a and which shaft (Z may be called the feed clutch shaft and the chain 0 passes id a jockey or guide pulley 0 (See A l and ie feed clutch shaft (Z is constantly 'en but at variable speeds by the means einafter described through chain and o'earin from a counter shaft all as cribcd and the chain wheel ned thereon a feed part clutch d certain times is engaged by a coacting part clutch (5 sh lably mounted upon the feed clutch shaft (Z but fixed therewith i s rotation by a key or feather and groove in the well known manner and the slidable part clutch (Z is intermittently thrown out of gear with the feed part clutch (Z so to leave its chain wheel cZ free upon the feed clutch shaft (Z at the times desired. See Fig. The slidable part clutch (Z is provided with an annular groove al therein which is engaged by a stud (Z upon one arm of a bell crank (Z the other arm of which has pivotally connected thereto one end of a feed clutch rod 6Z7 which near to its other end is pivotally connected to a radius arm d so that the rod (Z is vertically movable and at its lower extremity the rod (Z is provided with a truck or roller (Z which rests and runs upon the periphery of disk or wheel (Z which may he called the feed disk. (See Fig. 3.

The feed disk (Z is provided with a depression (Z in its periphery into which the truck or roller (Z of the clutch rod (Z is adapted to take so as to lower the rod (Z and turn the hell crank CZG upon its axis and thus throw the slidable part clutch (Z into engagement with the feed part clutch (Z at the times desired while when the truck or roller (Z runs upon the other or cylindrical of th peripherv of the feed disk the slidahle part clutch (Z is by the lifting of the clutch rod (Z disengaged from the feed part clutch (Z and the feed is stopped a spring a being employed to throw the part clutch (5 into gear and to keep the truck or roller (Z on the feed disk d (See Fig. 3.)

'lhe feed disk is intermittently driven by the following mea s z-Said disk (Z is fixed upon a shaft (Z revoluhly mounted in bearcarried by brackets (Z fixed to the table a and upon this shaft (1 is loosely mounted a compound wheel consisting of a spur wheel Z and pinion (l and the spur wiiecl a is constanly driven by a pinion e normally loose pen a countershaft con stantly driven ut variable speeds as here inafter des ribed by means of a chain wheel 0 fixed with the pinion c and a chain c and a chain wheel 6' fixed upon the main or first driven shaft which is provided with fast and loose pulleys c. (See Fig.

Fixed with the boss of the compound wheel (Z cl loose on the feed disk shaft (Z is a ratchet wheel (Z and filed with said shaft is a crank 6Z having a spring actuated pawl (Z i hich engages the ratchet wheel at certain times, that is when the feed is to be stopped, and rotates the feed disk shaft (Z and feed disk d but at other times the pawl (Z is disengaged from the ratchet wheel by means of a cam (5 upon a swinging bar d mounted upon an axis of motion which cam (Z is, by means of a cam Or incline (Z on the lower end of the swinging bar (Z brought into the path of an offset 6Z from the pawl (Z which latter is lifted out of gear with the ratchet wheel J when the feed is required to start and the truck or roller (Z of the movable feed clutch rod (Z at the same time enters the notch or depression cl in the feed disk (5 thereby allowing the rod (Z to fall, and throwing the feed part clutch d into engagement with the feed part clutch d and thus through the chain wheel at and chain giving motion to the feed regulating devices or cages hereinafter more fully referred to. (See Fig. 3.)

The swinging bar (Z is held with its cam (Z in the path of the offset al of the pawl d and is subsequently released, to allow the pawl (Z to engage the ratchet wheel al by the following means :Mounted upon the frame a of the machine is an electromagnet c1 placed in circuit with a battery 03 and provided with a horizontal armature c5 pivoted at cl to the frame a; and this ar1na ture (Z is formed with a downwardly projecting tooth, catch or detent d and in the revolution of the crank (Z the offset or roller 03 of the pawl cl engages the cam or incline (Z upon the swinging bar (Z19 bringing a projection el into engagement with the tooth or detent c 24 of the armature (Z thus holding the cam d of the swinging bar d in the path of the offest ri of the pawl (Z so that in the continued revolution of the crank al the offset ri of the pawl (Z will engage the cam (Z and thereby be held out of engagement with the ratchet wheel (Z until the magnet (Z is energized and the armature (Z is consequently attract ed and the detent (Z tripped or withdrawn from engagement with the projection cl upon the swinging bar (Z when the swinging bar d is allowed to resume its normal position by gravity and the pawl (Z under the influence of its spring 6 and the pressure of the pawl (Z upon the cam (Z assists to restore the swinging bar (Z to its normal position. (See Figs. 3 and 9.)

In order to prevent the pawl d" on its first engagement with the cam (Z in the revolution of the crank ai being thrown ofi the cam by centrifugal action; in which case it might travel beyond the cam 0P and reengage the ratchet wheel (Z and so miss one operation, an incline (Z is provided carried by the frame a and engages the offset (Z of the pawl c 17 and prevents that irregular action. (See Figs. 9 and 25.)

In case, on the breaking of the circuit, the armature should still be sufficiently attracted by the magnet d to hold the detent tooth (Z in its out of engagement position an inclined projection d is provided upon the armature (Z which is engaged by the offset (5 of the pawl (Z of the crank al in its revolution. See Figs. 9 and 25.)

At a certain period, that is after the weighing operation hereinafter described, is about completed the electric circuit is closed by the same contact making. device which. controls the out off shutters of the feed chambers 0*0 and which shutters are hereinafter described, so that the shutters are closed at the same time that the magnet 03 attracts the armature (Z and releases the swinging bar 03 permitting the spring d"** of the pawl cl to assert itself and cause the pawl d to again engage the ratchet wheel d and stop the action of the feed clutch shaft cl and therefore the feed as hereinbefore explained. (See Fig. 9.)

In the next revolution of the crank (Z the offset d of the pawl (Z engages the cam or incline d on the swinging bar d and again throws the cam (Z into the path of the offset ri of the pawl d and the projection of al of the swinging bar (Z into engagement with the detent cl of the armature (Z and the hereinbefore described. operations are repeated. (See Fig. 9.)

The pinion upon the counter shaft 6 which meshes with and drives the spur wheel (Z of the compound wheel (Z (Z of the feed disk shaft (Z has fixed therewith a chain wheel 6 which as hereinbefore described, is geared with the first or mainshaft 6 and the pinion 6 also has fixed therewith a part clutch 6 and the chain wheel 6 pinion c and the part clutch 6 are all fixed or formed together and loose upon the'counter shaft 6. (See Figs. 3 and 9.)

Slidable upon the counter shaft 6 is a coacting part clutch e which is fixed with the shaft 6 as regards rotation by means of a feather 6 and the part clutch 6 is provided with an annular groove 6 which is engaged by a roller 6* carried by a stud upon the forked arm of a bell crank lever e mounted upon an axis of motion 6 and the other arm of which bell crank is provided with a track or roller 6 which at certain times is acted upon by a cam i upon a cam wheel f loose upon the counter shaft 6. (See Figs. 1., 2 and 10.)

The cam wheel is provided with a pcripheral covering of leather f or the like which is engaged by a roughened wheel 9 fixed upon a lower shaft 9 which has fixed thereon a spur wheel g which meshes with the pinion 0 of the counter shaft e by which means the lower shaft g is constantly driven at a given speed. (Sec Figs. 1 and 9.) The cam wheel f however is not constantly driven by the lower shaft 9 but is intermittently rotated thereby by the following means :-.At a given point in its circumfer cnoe the periphery f of the leather covered cam wheel f is formed with a depression or dwell P so that when that part comes opposite the roughened wheel 9 of the lower shaft 9 the rotation of the cam wheel ceases and. it remains stationary while the slow feed which has previously commenced is continued that is to say that part of the feed of material to the packet i on the weighing frame 15* which takes place immediately before the required weighing is reached. (See Figs. 1 to 9.) The cam wheel f is held in this position by an arm f pivotally mounted at 7"" and provided with a hook like detent which at certain times
